英文摘要	The experience of application of a complex of near-surface geophysical methods (electrical resistivity tomography and soil-radon survey) for identification of fault zones in the platform cover of the Alakit-Markhinsky kimberlite field in Western Yakutia is presented. Surveys were carried out in summertime on the sites of Faynshteynovsky and Baytakhsky kimberlite bodies. In total, six profiles were passed: on each site, two profiles made over the kimberlite pipe, and the third one beyond the pipe boundaries. The methods applied have been shown to supplement each other and, despite the severe conditions of realization (high moisture content in a soil layer, existence of permafrost, etc.), allow fault zones to be identified. The structure of the fault zones in the top part of the platform cover corresponds to the early stage of fault formation. The soil radon anomaly of a faltering character and the subvertical anomaly of increased conductivity in the geoelectric cross-section correspond to the kimberlite containing zone. The discontinuous character of both anomalies analyzed jointly allows to allocate distinct fractures of the 2nd order, which are concentrated in the fault zone.
